  • Science Behind FD-47

    A vehicle's power systems suffer from regular wear and tear. As connections loosen and tolerances change, the power systems become more vulnerable to electrical noise over time.

    Fuel Doctor's ground-breaking technology allows the vehicle's computer systems to receive more accurate information through the power conditioning qualities of the Platinum FD-47. This helps restore the vehicle's lost efficiency in fuel consumption and power.

I have a 2002 Ford Excursion 7.3L diesel, 303,000 miles. 16 MPG before to 18 MPG after the Fuel Doctor! Immediately noticed smoother idle and improved overall performance.
